Specification of Letters Patent.

Patented Dec. 31, 1907.

Application iled June l5, 1907. Serial No. 379.235.

proved grip to be attached to mine cars andadapted to engage apropelling wire or cable, the object of the invention being to provide asimple construction by means of which a rod or cable can be securelyclamped and readily released.

I/Vith this object -in view the invention -consists in certain novelfeatures of construction and combinations of parts as hereinafter setforth and pointed out in the claims.

In the accompanying' drawings, Figure 1 is an elevation of a clampembodying my improvements. Fig. 2 is a rear view, and Fig. 3 is asectional. view.

l representsv the body portion of the clamp or grip provided at one endwith a base 2 having laterally projecting arms 3 spaced apart to receivebetween them a portion. of a mine car to which the clamp or grip is tobe attached. The arms 3 are provided with alined holes to receive a pin4 for locking the clamp to its support.

The body-portion 1 is provided with an overhanging aw 6 .having a curvedunderface to adapt said jaw to the wire or cable to be clamped. The body1 is provided near its base with a shoulder 7 and against said body 1and above the shoulder 7, a movable jaw S is disposed and provided inits upper end with a curved face similar to the curved face of the rigidjaw 6. Pins 9 are secured to the movable jaw 8 and pass throughelongated slots l() in the body l to guide said movable jaw in itsmovements, and suitable washers 1l. are located on the pins 9 to preventdisplacement of said movable jaw. The lower end of the movable jaw 8 isprovided with a curved-face 12 and between this face and the shoulder 7,near the base of body 1., -a cam 13 is located. The shank by means of acollar 16.

14 of this cam passes through a hole in the body l and is provided withan angular end to receive an operating lever l5. Displacement of the camand its shank is prevented A link 17 is pivotally connected at one endto the movable liaw S and at its other' end to the cam 13,-* said linkserving to insure the proper return of the' movable j aw'when theleveris operated to release the clamp from the rod or wire.

It will be seen that by moving the operating lever in one direction, thecam will be turned and, engaging the curved lower face of the movablejaw, force the latter toward the fixed jaw and cause the propelling wireor cable to be securely clamped or gripped between the jaws. By causingthe link to be so disposed that its longitudinal axis will cut the axison which the cam turns, the parts will be locked with the wire or cablebetween the two aws. When the operating lever is moved in the oppositedirection the parts will be unlocked, the movable released and the link17 will then serve to insure the return of the movable jaw, ashereinbefore explained.

Slight changes might be made in the details of my invention withoutdeparting from the spirit thereof or limiting its scope and. hence I donot wish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire tosecure by Iletters-Patent, is,

l. In a clamp, the combination with a body portion provided with a fixedaw, of a movable aw mounted on the body portion, a cam for operating themovable jaw and a link pivoted at one end to the movable aw and at theother end to the cam.

2. In a clamp, the combination with a body portion having elongatedslots and provided at one end with a .fixed aw, of a movable jaw, pinssecured to said movable jaw and passing through the elongated slots inthe body portion, a cam supported by the body portion, under the movablejaw, for operating the latter, and a lever connected with the said cam.

3. In a clamp, the combination with a body portion provided at one endwith a fixed jaw and at the other end with a base portion, of armsprojecting from the base portion adapted for attachment to a support, amovable jaw mounted on the body-portion, a cam supported by thebody-portion over 5 the base and under the movable-jaw for operating thelatterJ and a lever for operating the cam.

In testimony whereof, I have signed this speciiioation in the presenceof two subscribing Witnesses.
